Problems solved by technology

[0002] At present, the materials used for thermal insulation of external walls in buildings are generally room temperature foaming materials. The thermal insulation effect is not ideal and not durable. After installation, the facade needs to be reshaped. The cost is very high, and at the same time, harmful gases will be emitted during use, which will cause certain pollution to the environment

Embodiment 1

[0015] (1) First, mix 8.9Kg of glass powder with a fineness of 150 mesh, 0.4Kg of aluminum hydroxide powder with a fineness of 300 mesh, 0.35Kg of heavy calcium powder and 0.35Kg of light calcium powder with a fineness of 350 mesh to prepare a foaming mixture . In order to ensure the uniform mixing of materials, high precision of the proportion of batch materials is required, and all additives and glass powder must be fully stirred before entering the heating furnace. (2) First, spray the mold release powder on the inside of the molds of different specifications, and then put the foaming mixture prepared above into the mold and send it to the continuous roller table heating furnace. The foaming mixture in the mold is passed through the heating furnace. After preheating, heating for the first heating, sintering heating, heating for the second heating and foaming, annealing and cooling, a sintering foaming heater is prepared, and the mold containing the foaming heater is taken ou...

Embodiment 2

[0017] (1) First, mix 9.2Kg of glass powder with a fineness of 200 mesh, 0.3Kg of aluminum hydroxide powder with a fineness of 350 mesh, 0.25Kg of heavy calcium powder with a fineness of 400 mesh and 0.25Kg of light calcium powder to prepare a foaming mixture . In order to ensure the uniform mixing of materials, high precision of the proportion of batch materials is required, and all additives and glass powder must be fully stirred before entering the heating furnace.

Abstract

The invention discloses a glass pumice wall brick and a making method thereof. The glass pumice wall brick is prepared by sintering a foaming mixture, and the foaming mixture comprises, by weight, 85-93% of glass particles, 3-5% of aluminum hydroxide powder, 2-4% of heavy calcium carbonate powder and 2-4% of light calcium carbonate powder. The glass pumice wall brick contains blind hole foaming micropores, and can effectively obstruct air flowing; the diameter of the foaming micropores is 0.04-3 mm, the water-absorption rate is 0.2%, intensity is 3-8 MPa, and density is 0.5-0.6 g / cm<3>; the specific gravity is small and is only 0.3-0.8; the heat conductivity coefficient is small and smaller than or equal to 0.060 W / m.k (38DEG C). The glass pumice wall brick has the advantages of being light in weight, keeping warm, preventing fire, water and freezing, resisting acid, alkali and ageing, absorbing sound, being easy and convenient to construct, achieving integrated beatification of the appearance and saving engineering cost, will not pollute the environment during producing and using, and also has the advantage of achieving solid waste utilization of renewable resources.

Description

Technical field [0001] The invention relates to a glass light stone wall brick and a preparation method thereof. Background technique [0002] At present, the materials used for thermal insulation of exterior walls in buildings are generally foamed materials at room temperature. The thermal insulation effect is not ideal and not durable. The facade must be reshaped after installation. The construction process is complicated, and the production and installation The cost is very high, and at the same time harmful gases will be emitted during use, which will cause certain pollution to the environment Summary of the invention [0003] The purpose of the present invention is to provide a light weight, good thermal insulation effect, acid and alkali resistance, imperviousness, fire prevention, antifreeze, anti-aging, sound absorption, integrated appearance beautification, low installation and use cost, shorten construction period, and one-time paving solution All questions. Glass ligh...
